The area of Osat was liberated for a short time during the First Serbian Uprising (1804–13), under the leadership of Kara-Marko Vasić from Crvica. Upon the breakout of the uprising, Metropolitan Hadži Melentije Stevanović contacted Vasić, who met with the rebel leadership. After participated in battles on the Drina (1804), Vasić asked Karađorđe for an army to liberate Osat; Lazar Mutap was dispatched and the region came under rebel rule. In 1808, the Ottomans cleared out Osat, and by 1813, the rebels left the region. In the inter-war period, the population was divided between Orthodox and Muslim, with the Orthodox males commonly working as builders in Bosnia and Serbia.[1] They were differentiated by their neighbours through their traditional costumes and some traditions.[1]
